"Let It Go" remains on repeat during our morning commute and we're still pretty upset that talking snowmen don't actually exist. After breaking all kinds of movie and song records, Frozen the musical is up next!

Before Anna and Elsa hit Broadway, here are 20 things you don't know about this Academy Award-winning movie:

They modeled the reindeer, Sven, after Executive Producer John Lasseter's dog, Frankie! They actually brought in a real reindeer, but he just stood there and didn't move.

However, there are more Disney theories within the movie. Fans believe that when Elsa and Anna's parents left the kingdom, they were en route to Germany for Rapunzel's homecoming when their ship sank near Denmark. The second part of the theory is that the boat the parents were on is actually the sunken ship in The Little Mermaid. Where does The Little Mermaid take place? Denmark, of course. Disney can be so clever with their inter-weaving storylines.

Queen Elsa was originally supposed to be a villain. Thankfully they changed the story to make her misunderstood. The movie just wouldn't have been the same.
